Find an Airbnb in the same area, but use a different host. In my experience, Mo is not to be trusted.
The address is ok - but I would not recommend it for women travelling alone. It is located in a small alley to one of the bigger streets, but is far enough away from Sukhumvit to make a girl feel unsafe after dark. The place itself is nice - a typical Bangkok flat, clean and simple, not new building, but with a wonderful maid. I would recommend you to look for something like this, but another host.
Mo, unfortunately, turned out to be the Airbnb host you do not want to deal with.
First, she asked for payment in cash. She only accepted other when I insisted on paying via Airbnb.
After we had made a written agreement/ discount for 3 check-ins and 18 days in total, I made two payments for all the check- ins, during the first check-in. When I was informing about my arrival for the 2nd check-in, she seemed to have no idea about this. I sent her copy of our messages on Airbnb, and receipts for my payments, and heard...nothing.
To sum up, she cancelled the two last check- ins, kept the money ( approx 400 USD), and as a consequence, I had to find alternative accommodation. I even gave her a chance to fix this. From my point of view, she seems like a dishonest host, and I recommend people to have no dealings with her.
